New Plugin gets 'This ANSI plugin is not compatible with your Unicode Notepad++'browsing

I’ve created a sample Plugin derived from NppPluginTemplate. Its compiled with Embarcadero’s C++ Builder as a 32 Bit application and with UNICODE. The function isUnicode() is build and exported from the DLL. But if i start Npp i get the messagebox:

This ANSI plugin is not compatible with your Unicode Notepad++

NppPluginDemo.dll is not compatible with the current version of Notepad++

I have it now. I compiled the plugin template without any changes. The only thing was, the C++Builder has a project option ‘C++ Compiler/Output/Create Underscore for Symbolnames’, which is checked by default. It must be unchecked.

Conclusion, Npp Plugins can also developed with Embarcadero’s C++ Builder.
